Answer:
Option - E is the same distance from A and B.
Explanation:
Perpendicular bisector can be understood by this explanation:
If line n is intersected by line n at the center of line n
, then line m is the perpendicular bisector of line n
There are 4 right angles formed due to this perpendicular bisector around this mid-point
∵ Line CD ⊥ of segment AB
∴ Line CD intersects segment AB at the middle point of AB
∵ Line CD and segment AB intersected at point E
so, E ∈ AB and E ∈ CD
⇒ Point E is the mid-point of line AB
⇒ E is the same distance from A and B.
Thus, the correct option is - E is the same distance from A and B.

Explanation:
White blood cells are especially active when you are sick because their primary job is to fight off infections – often bacteria or viruses that do not belong in you. Once they locate the invader making you sick, they eat it and destroy it. What organelle do you think is plentiful in white blood cells?
Answer:
Lysosomes
Explanation:
Lysosomes are membrane bound organelles that contain degradative enzymes. They degrade worn-out cellular parts and may also be used by cells to degrade/destroy invading bacteria or viruses. Hence, since white blood cells are primarily responsible for fighting infections, it is expected that they have a high amount of lysosomes (which they indeed do have in high amount).

4. a. viral genome is replicated using host cell's machinery
5. d. new viruses are assembled within host cell
6. e. the cell ruptures and releases new viruses to infect new cells
Explanation:
First, the virus attaches to the cell. Then it penetrates the cell membrane and inserts its genome inside the cell. The virus relies on the cell machinery to synthesize its proteins, and also to replicate its genome.
With these components being synthesized and replicated, new viral particles are assembled inside the host cell. Eventually, the cell ruptures, and the newly assembled viruses are released and able to attach to new cells to repeat the cycle

in what ways is ATP like a fully charged battery?
Answer:
ATP ATP can be compared to a fully charged battery because both contain stored energy, whereas ADP resembles a partially charged battery. Releasing Energy From ATP The energy stored in ATP is released when ATP is converted into ADP and a phosphate group.
Explanation:
The ATP molecule is comparable to a battery that can be recharged. It is ATP when ultimately charged. It's ADP when it's worn out. When the battery runs out, it is simply recharged rather than discarded.
What is ATP?A vital "energy molecule" in all living things is adenosine 5′-triphosphate, also known as ATP and typically written without the 5′-. In particular, it is a coenzyme that transfers cells' energy by liberating its phosphate groups when it interacts with enzymes like ATP triphosphatase. The molecule comprises an adenine bicyclic system, a furanose ring, and a triphosphate chain.
The discovery of ATP was announced in 1929 by two research teams. It was isolated from mammalian muscle and liver by Cyrus H. Fiske and Yellapragada Subbarow at Harvard Medical School (Boston). Karl Lohmann discovered it in muscle tissues while working for the Kaiser Wilhelm Institutes in Berlin and Heidelberg.
Over the next 15 years, ATP separation from other sources came next. In 1987, Koscak Maruyama of Chiba University (Japan) provided a thorough analysis of ATP's discovery and structural elucidation.
Therefore, ATP is like a rechargeable battery because it can be recharged and discharged.

Number of deer and insects
Types of trees and plants
Rainfall and the location on the mountain
Predator and prey population
Answer:
Rainfall and the location on the mountain
Explanation:
This is the answer because:
Rainfall highly helps the trees on the mountains grow. The location of a tree also matters a lot because it has to be in a spot where it can reach sunlight and lots of rain.
Therefore, the answer is Rainfall and the location on the mountain.

a student makes a claim that a cell is undergoing the process of transcription . What evidence woul
d be present to support his claim
Question:
The complete question has these options:
A) tRNA with anticodons is carrying amino acids to the ribosomes.
B) DNA polymerase is using both strands of DNA to produce multiple RNA molecules.
C) Ribosomes are reading mRNA molecules three nucleotides at a time to synthesis proteins
D) RNA polymerase is using a single strand of the DNA molecule as a template for mRNA production
Answer:
D) RNA polymerase is using a single strand of the DNA molecule as a template for mRNA production
Explanation:
During transcription, RNA polymerase uses DNA as a template to create a new molecule of mRNA via complementary base pairing
A) tRNA with anticodons is carrying amino acids to the ribosomes. - this is not evidence of transcription but is instead evidence of translation
B) DNA polymerase is using both strands of DNA to produce multiple RNA molecules. - this is false, DNA polymerase is the enzyme that performs DNA replication not transcription.
C) Ribosomes are reading mRNA molecules three nucleotides at a time to synthesis proteins - this is not evidence of transcription but is instead evidence of translation
D) RNA polymerase is using a single strand of the DNA molecule as a template for mRNA production - this accurately describes the process of transcription.
How does the property of cohesion make farming possible?
Answer:
cohesion refers to the attraction of molecules for other molecules of the same kind, and water molecules have strong cohesive forces to make the crops grow faster
Explanation:
Answer:
Cohesion is the forces holding water molecules together. This concept was covered when talking about properties of water and capillary action. You may remember capillary action is like when you have a little bit of water in the bottom of your cup but the water in the straw is a little bit higher than the water in the cup. Because water is polar - meaning it has a somewhat negative end and a somewhat positive end - it is attracted to other water molecules and other substances, such as the straw.
Cohesion
Now, you may be asking yourself: what does a straw have to do with xylem? Well, just like the water moving up the straw, water moves up xylem. The movement of water in plants is from the roots up through the shoot and out the leaves. Part of the reason for this movement of water is cohesion. The water molecules within the xylem tend to stick together, which allows them to help pull other water molecules up through the xylem - even against the flow of gravity.
When water is moving through the xylem, it is moving between different vessels or tracheids. It is very important that these elements are tightly held together because if there are air bubbles, the effects of cohesion are diminished. That is, if air bubbles get into the xylem, the water will no longer move up through these tubes. We can relate this idea back to our straw. If you have ever had a straw that has even a tiny hole in it, you know that it is very hard - even with the aid of suction - to get the water through the straw and up to you. This is what happens if air bubbles get into the tubes of the xylem.
So , indirectly cohesion helps in farming through xylem....

How are fossils that contain vestigial organs consistent with common ancestry?
Answer:
Explanation:
La evidencia de un antepasado común en los seres vivos, que han encontrado durante décadas científicos que trabajan en numerosos campos, demuestra la descendencia común de estos seres, que la vida en la Tierra se desarrolló a partir de un último antepasado universal, que la evolución existe y que puede demostrar los procesos naturales que han dado como resultado la biodiversidad de la vida en la Tierra. Esta evidencia apoya la síntesis evolutiva moderna, la actual teoría científica que explica cómo y por qué cambia la vida a lo largo del tiempo. Los biólogos evolucionistas han documentado evidencias de antepasados comunes realizando predicciones verificables, probando hipótesis y desarrollando teorías que ilustran y describen sus causas.
La comparación de secuencias genéticas de ADN ha revelado que los organismos filogenéticamente próximos tienen un mayor grado de similitud secuencial que los organismos filogenéticamente alejados. Se pueden encontrar más pruebas de la descendencia común en detritus genéticos como los pseudogenes, regiones del ADN ortólogas a un gen en un organismo relacionado, pero que ya no tienen actividad y parecen estar experimentando un proceso continuo de degeneración por acumulación de mutaciones.
A carbon atom has 6 protons and 6 electrons. Carbon has three naturally occurring isotopes, carbon-12, carbon-13, and carbon-14. Which of these statements is true about carbon and its isotopes? A.All carbon atoms have six neutrons. B.All carbon atoms have six protons and six electrons. C.Atoms of all carbon isotopes have either more than 6 electrons or fewer than 6 electrons.
Answer:
The correct option is B
Explanation:
Isotopes of the same element have the same atomic number (number of protons) but different mass number. Hence, all the three naturally occurring carbon isotopes mentioned in the question have 6 protons each. Since the number of protons in a neutral atom is equal to the number of electrons in the same atom, each of these isotopes also have 6 electrons.
However, to determine the number of neutrons in each atom, the number of protons (atomic number) is subtracted from the mass number.
Hence, the number of neutrons in carbon-12 is 12 - 6 = 6
the number of neutrons in carbon-13 is 13 - 6 = 7
the number of neutrons in carbon-14 is 14 - 6 = 8
From the explanation above, it can be noted that the number of protons and electrons in isotopes of the same element are the same while the number of neutrons in these isotopes are different. Hence, the correct option is B
